RSS auto-discovery is a way that makes possible for web browsers and services to automatically detect a blog's RSS. It's also a way to inform blog readers that they can follow blog's updates easily via a news feed reader. To learn more about how RSS works, please check this link.
Usually blog platforms enable blog feeds automatically, so that blog readers can follow blog updates, as well as services that rely on blog feeds can function properly.
If RSS auto-discovery is not enabled, normally you'll get an alert that your blog doesn't have an RSS while you submit your blog with us. Generally, you should be able to find options to enable feeds in your blog control panel. Here's how to enable RSS for *blogspot.com blogs:
• Log in to blogger.com and click on "Settings" and then "Other";
• Look for "Site Feed" section and make sure that "Allow Blog Feed" is not set to "None".
Alternatively, enabling RSS can be done manually by adding a simple line of code in the header of the blog, referring the actual RSS feed of the blog. The following line of code should be added somewhere between
</head>tags in blog's html:
<link rel="alternate" type="application/rss+xml" title="TITLE" href="RSS-URL" />
RSS-URLaccordingly to point to the RSS of your blog. It is recommended setting only one RSS feed URL for auto-discovery, in order to make sure the right content is distributed from your blog (e.g. getting your blog comments retrieved from the RSS rather than the actual blog posts).
Completing the above, could overcome certain warning messages shown when you submit your blog to BlogUpp or other blog services. Note as well that empty RSS post titles prevent us from making use of your blog posts in order to promote the blog. If that is your case - please consider adding titles and then resubmit your blog.
Feed errors may also be caused when certain uncommon symbols are written in blog posts, resulting in feed parsing errors. Some web browsers will not report such errors, so you won't be aware of eventual issues. Internet Explorer and Opera web browsers are more sensitive to such errors and report them accordingly. Please consider checking your feeds in these browsers from time to time.
